Lenses use the idea of refraction. When light enters a MORE DENSE medium it slows down. Optical density is measured by the refractive index, n. The larger the difference between the indices at an interface, the larger the angle of refraction for light rays crossing the interface.
1. Calculate the speed of light for the following mediums: a. Water (n=1.33); b. Diamond (n=2.42) c. Plexiglas (n=1.51) 2. Calculate the refractive index for a substance if the speed of light in that medium is.

Snell’s Law Worksheet. Name_________________ Important stuff: n = index of refraction of a material. v n c c = speed of light in vacuum = 3.00 x 108 m/s. v = speed of light in the material. Snell’s Law. 3) For each of the drawings below, rank the indexes of refraction from smallest to biggest.
Calculate the angle of refraction.
A ray of light traveling from air into crown glass strikes the surface at an angle of 30 degrees. What is the angle of refraction? (air n=1, crown glass n=1.532)
Refraction of Waves. Refraction is the process of where waves change direction as a result of moving from one medium to another. This section looks into the idea of refraction and how to calculate the refractive index of a medium.
